Process for producing an electrode with positive temperature coefficient (PTC) function |
摘要 |
Conventional batteries have the problem that, when battery temperature rises above a temperature at which the separator melts and flows due to an internal short-circuit, a large short-circuit current is generated between the positive and negative electrodes, that further raises the battery temperature. As a result, the short-circuit current further increases. The inventive electrode increases its resistivity with increasing temperature, and a processing for producing the electrode is disclosed. The electrode of the invention has an electron conductive material containing a conductive filler and a resin and increases its resistivity with increasing temperature.
